Sixteen hours are to one day as twenty days are to June's length.

Sure, let's break this down:

1. First, we need to understand the relationship between the first pair of quantities. Sixteen hours is a part of one day. Specifically, it is 16/24 or 2/3 of a day.

2. We need to apply this same relationship to the second pair of quantities. We know that June has 30 days. So, we need

Sure, let's break this down:

1. First, we need to understand the relationship between the first pair of quantities. Sixteen hours is a part of one day. Specifically, it is 16/24 or 2/3 of a day.

2. We need to apply this same relationship to the second pair of quantities. We know that June has 30 days. So, we need to find out what quantity is to 30 days as 16 hours is to one day.

3. To do this, we multiply 30 days by 2/3. The result is 20 days.

So, the statement is saying that 16 hours is to one day as 20 days is to June's length. This is a correct statement because 16 hours is 2/3 of a day and 20 days is 2/3 of June.
